In 2011, RE provided 20.1% of the total electricity capacity of the world. Of the total electricity capacity from RE, solar power accounted for 1.4%, geothermal 1.6%, biomass 9%, and wind power accounted for 10%, the rest 78% being from hydro. On the basis of the IEA data, the annual growth rate of solar power was 50%, whereas that for biomass, wind, geothermal, and hydropower was 12%, 25%, 4%, and 2%, respectively. Assuming these annual growth rates to continue to 2025, find the fractions of each of these renewable energies in electrical power capacity in 2025, if the annual growth rate of total electricity capacity is 2.4% (based on IEA growth scenario).

Q2.
If the total world electrical power capacity grows at a rate of 3% during this period (based on IEA growth scenario), what fraction of the total electricity capacity in 2030 will be from (a) RE and (b) solar energy?
